I bought this navy blue dress by Jil Sander http://www.jilsander.com at the consignment store Clothes Heaven in Pasadena, CA. The dress is a light stiff cotton, the neckline has a ruffled hem, and there are stitching details above the pleats. It is, like most perfect dresses, easy to wear and sophisticated. It can be worn anywhere and yet it is so lightweight that it can handle an Umbrian heatwave. Shoes? Repetto, certo!
